S6906 Bearing Product Overview & Core Advantages
The 6906 metric ball bearing is a single row deep groove ball bearing engineered for high-performance radial load applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance and is designed for precision operation with an ABEC-1 tolerance class. Its compact design, with a 9 mm width, makes it ideal for applications where space is limited but reliability is critical. This bearing requires lubrication and operates effectively across a wide temperature range from -86 to 230 °F.
S6906 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6906 | Standard metric series designation indicating a 30 mm bore, 47 mm OD, and 9 mm width. |
| Open | No seals or shields, allowing for higher speeds and easy re-lubrication. |
| ABEC-1 | Precision tolerance grade ensuring consistent running accuracy. |
| C0 | Standard radial internal clearance group (0.006mm to 0.020mm). |
S6906 Bearing Structural Features & Performance Benefits
- High Corrosion Resistance: The all-stainless steel construction (rings, balls, cage) provides superior protection in harsh environments and complies with ROHS and REACH standards.
- Radial Load Capacity: The deep groove raceway and single-row design are optimized to handle the specified radial dynamic load rating of 1465 lbf and static load rating of 1014 lbf efficiently.
- Precision Performance: Manufactured to ABEC-1 tolerances with controlled internal clearance (C0), ensuring smooth, low-vibration, and low-noise operation.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 12,600 rpm, suitable for demanding applications.
S6906 Bearing Typical Application Areas
This precision bearing is widely used in:
- Medical and Dental Equipment
- Food Processing and Packaging Machinery
- Precision Instruments and Optical Devices
- Small Electric Motors and Pumps
- Agricultural and Marine Equipment (where corrosion resistance is key)
